VALVE OIL-FILLED ELECTRIC MOTOR Russian patent published in 2020 - IPC H02K5/12 H02K5/132 H02K5/167 H02K5/20 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, to valve oil-filled electric motors, which are part of small-sized plants for electric-centrifugal pumps. Valve oil-filled electric motor includes housing, n modules of stator with phase windings laid in grooves and n modules of rotor with permanent magnets, installed in housing on intermediate and end supports. Spline couplings connect and position rotor modules relative to similar poles, and also connect rotor module with current lead head shaft. End flanges tighten and position stator modules relative phase winding of the same name. Radial-axial bearings are installed on each rotor module. In the support body there are holes for local supply and circulation of oil in bearings.

EFFECT: technical result consists in uniform distribution of axial load of rotor on all modules of rotor and increase of amount of removed heat from bearings.
